Preheat your oven to 350°F (175°C). Prepare your baking sheet with parchment paper or a silicone mat.

Cream together the softened butter, granulated sugar, and brown sugar until light and fluffy, about 2-3 minutes.

Add eggs and vanilla extract, and beat on low speed until well combined.

In a separate bowl, whisk together flour, baking soda, and salt. Gradually add dry ingredients to wet, mixing gently until just combined.

Fold in the chocolate chips or other mix-ins gently.

Scoop dough onto the prepared baking sheet, spacing them about 2 inches apart.

Bake for 10-12 minutes until edges are golden brown, with slightly underbaked centers.

Let cool on the baking sheet for about 5 minutes, then transfer to a wire rack to cool completely.
